When the pressure in the bag reduced to the level which is not enough to open the valve, the valve will close automatically. Meanwhile, the valve will automatically open only when the pressure inside the bag is higher than the pressure outside the bag, otherwise, it will not open, and the air outside will not enter to the bag.Detailed Photos A degassing valve is a one-way vent that allows coffee beans and ground coffee to slowly release carbon dioxide (CO2) and other volatile gases from the bag, without coming into contact with the air outside.Recommended Products   Packaging & ShippingPackaging: Plastic film and carton CartonPacking: 12,000 pcs/ctn, 55*35*39cm Company Profile  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
